Fuse Mobile Launch New UK Multi-Network eSIM Mobile Broadband Service
A new eSIM focused virtual mobile provider has recently launched called Fuse Mobile, which as the name suggests is designed to provide consumers with mobile data plans than can automatically harness the 4G and 5G networks of EE, Three UK, Vodafone, and O2 through a single eSIM plan.
The service, which will automatically connect your mobile phone to whichever network has the strongest signal, is intended to help overcome the areas of weak signal that often exist in certain areas between different mobile networks. In addition, on the operator’s Pulse and Surge plans, your data allowance will also work in 130+ countries abroad “at no extra cost“.
The catch with multi-network operators like this is that their plans often have fairly limited data allowances and don’t come with the usual unlimited calls + texts features. Fuse currently has just three monthly plans, all on a multi-network eSIM: Spark (5GB of data at £5.99 a month), Pulse (10GB + roaming in 130+ countries at £9.99) and Surge (15GB + roaming, £14.99). Every plan is rolling monthly with “no contract“.

In addition, new customers are being invited to try the service free for its first 7-days of service and Tethering (Hotspots) are supported on all plans. We should point out that Fuse aren’t the first eSIM provider to come up with such a product, with Anywhere eSIM being able to do something similar, albeit based around more of a pre-paid model (i.e. you pay £50 for 12-months and that gets you 1,000 minutes, 1,000 texts and 10GB of data) – acting as a secondary SIM.

I presume this is within the same group of companies as Fuse Energy, sponsors of The Rest Is Politics podcast. I’ll watch out to see if Rory & Alistair start plugging them.
you presume incorrectly.
They have nothing to do with each other.
Very limited amounts of data almost too restrictive.
The intention of this isn’t really to be your main SIM, it’s supposed to be a backup SIM if you’re in an area that your main provider doesn’t have coverage but another one of the providers does.
Flexifone is still working well for me 12 months on and seems to offer a lot more data than this. But the roaming element here looks good.
The only caveat for me is that it’s ‘strongest signal wins’ (makes sense, easy to measure without significantly impacting on battery life etc.) According to their support, what you can’t do is manually over-ride the network selection so if your strongest signal is also massively congested, tough – you can’t change to another network manually.
I get the technical limitations and that the vast majority are more likely to want their backup to switch automatically wherever possible, but for those who want to have that granular control, this isn’t necessarily the best solution. I’ll stick with my £1 Sky Mobile eSIM and £2.50 Lebara SIM as my backup to my main EE service. It’s more manual and faffy, but at least I can be a control freak about it!
Not convinced that this is truly ‘Multi-IMSI’ or that all 4 UK operators are available to roam on, at least from what I’ve observed.
From my testing I can only connect to 3UK (PLMN: 23420) or Telefonica O2 (PLMN: 23410). Both Vodafone and EE are seemingly unavailable for me to join via manual network selection. The IMSI given to my eSIM is registered to Telecom Italia and does change over either network that I can connect to so I don’t see how they can claim this as ‘Multi-IMSI’ (which they do on their website). This just seems like a fairly standard multi-network eSIM with roaming capability unless there is something else going on ‘under the hood’.
No mention of calls/texts allowances on their website?
As per the article: “The catch with multi-network operators like this is that their plans often have fairly limited data allowances and don’t come with the usual unlimited calls + texts features.”
BNE SIM offer 10gb of data that doesn’t expire works across multiple networks in the UK and Europe for 12 euros, if you want a back up eSIM why would you go with the above?
